The new Bhoys signing looked very sharp indeed - but the skipper stole the limelight at the end.
Indeed, the former Dundee United forward can be seen chatting to the likes of Virgil van Dijk and Stuart Armstrong, as well as joining in with the practice drills and showing a good touch.
In shooting training, meanwhile, was where Ciftci excelled. Some of his shots found the top corner with ease, while he again showed a great touch in teeing team-mates up.
Sadly for the 23-year-old, though, Celtic captain Scott Brown stole the show at the end of the video, beautifully chipping the goalkeeper and celebrating after leaving the shot stopper absolutely stranded.
Ciftci controversially clashed with Brown last season but will now be the beneficiary of the Bhoys skipper's quality as his new team-mate. And what better way to show who's boss than by slotting the ball home with the ultimate calm and composure?
Celtic will be in action for their third friendly of pre-season later tonight, as Ronny Deila's men take on David Moyes' Real Sociedad side at 7.45pm (British Time).
